description

0445120126 serves as the core fuel injection component for Mitsubishi D04FR diesel engine of Kobelco SK140 excavator.Widely installed on Kobelco SK140‑8 series medium‑size construction machinery, it adopts Bosch high‑pressure common rail fuel technology, delivering ultra‑fine fuel atomization and accurate fuel metering under heavy‑load and long‑time continuous operation conditions. It effectively resolves typical faults triggered by injector aging and wear, such as insufficient engine power, unstable idling, black smoke emission, difficult cold‑start, slow throttle response and excessive fuel consumption. With consistent OEM parameters and good interchangeability, it supports original‑position direct replacement without extra modification, making it an ideal replacement part for routine maintenance and engine overhaul of Kobelco SK140 excavator.
